Key featuresFeatures of the AI Voice Generator
AI voices in over 177 languages and dialects
Browse 300+ natural-sounding AI voices across a wide variety of accents and 177+ languages and dialects. Optimise for a regional accent, switch genders, or layer in cultural flavour without booking voice actors. Every text-to-speech voice created here offers studio-grade voice quality, suitable for narration, promotional videos, and podcasts.
Tone, pace, and intonation control
Direct the performance line by line. Adjust pacing, stress key phrases, soften punctuation pauses, or push the energy up for a punchy social clip. Your script reads with the intonation and emotion you’d use, not a robotic, computer-generated TTS algorithm.
Voice cloning from a short sample
Clone your own voice in about a minute and use it as your signature narrator across every video, course, or podcast. Train it once with AI voice cloning, then keep the same delivery across thousands of high-quality generations.
Multilingual AI dubbing with lip sync
Dub any voiceover into 177+ languages and dialects with AI dubbing that keeps tone, timing, and natural cadence intact. Pair the voice with the AI video translator and your presenter lip-syncs the new language on screen.
Built-in video editing tools and subtitles
Drop the voice you created straight into the AI video editor alongside visuals, music, and auto-captions. Skip the export-import shuffle across three different tools to make your video. You get one workspace to streamline content creation from script to share-ready file.
Use cases
Faceless creators spend hours recording, retaking, and editing audio. Paste your script, generate AI voices that match the tone, and publish a vertical or 16:9 clip the same day, ready for any social feed.
Online courses succeed or fail on engaging narration. Create voiceovers for every lesson in multiple languages, refresh training materials without re-recording, and add subtitles automatically with the subtitle generator for accessibility.
Hiring narrators is slow and expensive, and DIY audio rarely works well. Pick an expressive voice, generate chapter by chapter, and produce a finished audiobook with a consistent tone and natural-sounding speech across hundreds of pages.
Replace a paid voice actor for your intro, mid-roll advert, or sponsor spot. Type the spot, choose a voice that matches your show's energy, and drop a polished read into your edit in under five minutes.
Marketing teams need professional voiceovers for every campaign, region, and asset. Personalise and localise in 177+ languages and dialects, and pair reads with a product demo video, so launches go live the same week your script arrives.
Global teams need consistent training in every language. Write a single script, automate AI voice generation across 177+ languages and dialects, and deliver a multilingual training video library without ever stepping into a recording studio.
